There is an apocryphal story about Gandhi, said to have taken place when he was working as a lawyer in London. It was unusual for an Indian to have an Englishman working under him, but Gandhi had an English assistant. One day Gandhi asked him to do something and the Asssistant asked,
Mr. Gandhi, is that an order or a request?
If you do it, it would be a request.
Gandhi did not have to ask a second time.
Hard to know for sure if it really happened.
